BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 762,745, dated June 14, 1904.

Application {iled January 27, 1904. Serial No. 190,813. (No mnodel.)

To a/ZZ whom it may concern:

Be it known that I. CHARLES E. MoMANUs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia` and State of Pennsylvania, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

This invention relates to new and useful improvements in bottle-closures; and the primary object of the same is vto provide means in connection with the mouth of a bottle, jar, or analogous device for permitting expeditious application and securement of a cap thereto and for allowing `'repeated use of the same cap.

In ordinary formsof bottle-closures as heretofore constructed screw-caps and caps with inwardly-projecting lugs movable in straight Athe mouth or outlet thereof, in which at regular intervals downwardly-inclined or oblique slots are formed and adapted to receive similarly-disposed lugs projecting inwardly from the lower extremity of the cap, the latter whe i applied to the rim being pressed downwardly and given a rotary movement through the medium of the angularity of the slots and lugs, a continued rotation of the cap Within predetermined limits after the lugs have been pressed through the slots causing the upper ends of said lugs to bear against the under edge of the rim.

In the drawings, Figure 1 is a side elevation of a portion of a bottle-neck embodying features of the invention and showing the cap thereon in section. Fig. 2 is an enlarged top plan view of the bottle-neck, illustrating the angular slots extending downwardly through the rim thereof. Fig. 3 is a horizontal section on the line 3 3, Fig. 4. Fig. 4 is a transverse vertical section on the line 4 4, Fig. 3,

4 a cork filling forming part of the invention being shown in edge elevation.y

Similar numerals of reference are employed to `indicate corresponding parts in the several views.

rIhe numeral l designates a bottle-neck having a circumferential rim or bead 2 around the'mouth thereof, and in this rim or` bead at regularvintervals are grooves or slots 3, which extend through the upper and lower edges of said rim and are disposed at similar, angles of inclination, the angles of these slots being about forty-five degrees. A cap 4, of metalor other suitable materiahpreferably of cylindrical form, is provided and is fully open at the bottom and closed at the top. Extending inwardly from the lower extremity of this-cap and terminating at its lower edge are lugs 5,-

which are inclined similarly to the grooves or slots 3. When the capV 4 is pushed downwardly in applying the same, the angular structure of the grooves or slots 3 and the lugs 5 causes the cap to have a rotary movement imparted thereto until the -upper ends of the lugs reach the bottom or lower terminals of the grooves or slots, when the cap is manually rotated to bring said upper ends of the lugs under the rim or bead 2between the lower open terminals of the grooves or slots. In some instances the downwardly-increasing diameter of the bottle-neck below the rim or bead 2 will be suflicient to jam the lugs 5 and cause the'latter toV stay in close contact with the under edge of the said rim or bead. To render the closure more effective, however, a filling 6, of

`cork or other suitable material, is inserted in the upper part of the cap and has its lower surface at such distance above the upper ends of the lugs as to be forced tightly down against the upper edge of the rim or bead 2 when the cap is fully applied. Moreover, when the cap is applied the side iiange thereof is held in close contact with the edge of the rim or bead, as clearly shown by'Fig. 1. After the cap has been applied, as set forth, it can be removed at any time desired `and preserved for subsequent use by rotating the same until the upper ends of the lugs 5 aline with the lower open terminals of the grooves or slots 3, when FSO an upward-drawing tension on the cap will cause the lugs to move through the grooves or slots and impart a rotating movement to the cap in a direction the reverse to that when the said cap is applied. If preferred, however, the cap can be forced 0H the bottle-neck by means of a suitable tool. This latter operation can be pursued when it is undesirable to preserve the cap for subsequent application.

The lugs can be applied to or formed with the inner face of the cap by any suitable means, and in some structures the said lugs may be struck inwardly from the cap, particularly when the latter is formed of sheet metal.

Changes in the contour, proportions, and dimensions of the parts embodying the features of the invention may be resorted to without departing from the spirit of the latter'.

Having thus fully described the invention, what is claimed as new isl. A'bottle or analogous device, having a rim outstanding from the neck thereof and provided with a series of downwardly-extending angularly-disposed grooves which open through the upper and lower edges of said rim, and a cap having lugs projecting inwardly from the lower portion thereof and arranged at angles corresponding to those of the grooves and movable through the latter to engage the under edge of the rim.

2. A bottle or analogous device, having a rim surrounding the neck thereof and located adjacent to the outlet of the same, the said rim being formed with downwardly-inclined slots therethrough at regular intervals, all the slots inclining in the same drection, and a cap having means to engage the upper edge of the rim and also provided with lower inwardly-projecting lugs arranged at angles of inclination similar to those of the grooves and depressible and withdrawable through the latter, the upper ends of the lugs bearing closely against the under edge of the rim when the cap is applied.

3. A bottle or analogous device, having a neck with a rim surrounding the outlet extremity thereof and formed with a downwardly-inclined groove, and a cap arranged to fit over said rim and provided with a lower inwardly-extending lug arranged at the same angle of inclination as and movable through said groove to engage the under edge of the rim.

4. A bottle or analogous device, having a neck with a rim surrounding the outlet end thereof and formed with down wardl y-inclined grooves opening through the upper and lower edges of said rim, a cap to lit over the rim, having an upper filling, and inwardly-extending lugs at-the lower portion of the cap arranged at angles of inclination similarly to the grooves and bearing against th'e under edge of the rim when the cap is applied, the distance between the upper ends of the lugs and the filling being approximately er] ual to the thickness of the rim.

In testimony whereof I aiiix my signature in presence of two witnesses.
